FIELD: agriculture. ^ SUBSTANCE: head of vibratory air separator mill is made in form of trapezium limited with short and long inclined walls and contains air equalising device in form of perforated strips. The short inclined wall consists of two vertically installed plates equipped with a pivot. One of the plates is designed to turn in the direction of the long wall. An apron made out of air tight material is attached to the lower portions of the plates. The perforated strips are located parallel to the long inclined wall. The area of the effective cross-section of the perforated strips diminishes proportionally to heights of grain material situated thereon. ^ EFFECT: high quality of grain material cleaning at transverse tilt angle of head equal to zero. ^ 2 dwg
